What is the molarity of a 250.0 milliliter aqueous solution of sodium hydroxide that contains 15.5 grams of solute? 6.2 M
2 answers:
Moles = 15.5 g / 40 g/mol = 0.3875 mol M = 0.3875 mol / 0.250 L = 1.55M
Answer : The molarity is 1.55 M
Explanation :
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
or,
In this question the solute is, sodium hydroxide.
Now put all the given values in this formula, we get:
Therefore, the molarity is 1.55 M
